Experiments performed on CBA mice thymectomized in adult life, exposed to lethal doses of irradiation and given tissue therapy are described. Marrow, foetal liver, or spleen cells from syngeneic donors could protect the mice against the lethal effects of irradiation. Between 30 and 70 days' postirradiation, however, marrow-treated, thymectomized irradiated mice showed evidence of trophic distur...

Osteoblasts, osteoclasts, chondrocytes, and macrophages that participate in the bone repair process are derived from hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs). However, the roles of these stem cells during the repair of injured bone tissue are still unclear. In the present study, we examined the effects of bone defect on HSCs and MSCs in bone marrow and spleen in 75 mice...

Using an immunoperoxidase technique that permits optimal antigen localization at the light microscope level. we have detected two platelet a-granule constituents and three platelet membrane glycoproteins in mouse bone marrow megakaryocytes and in murine megakaryocyte colonies grown in soft agar culture for three to seven days. Using polyclonal antibodies prepared against human platelet proteins...

acute myeloid leukemia (aml-m7) is a type of pediatric aml accounting for 3–10% of primary childhood aml and children may present with a broad variety of symptoms including low-grade fever, diarrhea, easy bruising, failure to gain weight and life-threatening conditions. we report a rare case of aml .a 26-month-old boy who presented with weakness and fatigue. he was diagnosed as a case of amlm-7...

background: anti-hla-antibodies are known to affect the allograft survival in transplant recipient patients. objective: the aim of this study was to evaluate the association between anti-hla antibodies and kidney allograft outcomes, particularly in recipients with concur-rent donor bone marrow cell infusion (dbmi). methods: between june 2006 and may 2007, forty living unrelated donor kidney tra...

The myeloproliferative diseases (MPDs) or myelo-proliferative neoplasms (MPNs) are a group of diseases of the bone marrow in which excess cells are produced. Chronic idiopathic myelofibrosis (CIMF) is a stem cell defect characterized by splenomegaly with multiorgan extramedullary hematopoiesis, immature peripheral blood granulocytes and erythrocytes and progressive bone marrow fibrosis. The mos...

Aim—To investigate whether spectrin can be used as an immunohistochemical marker for erythroid precursors in routinely processed paraYn embedded bone marrow sections. Methods—Bone marrow biopsies and clot sections were stained with rabbit antihuman erythrocyte spectrin antibodies, specific for erythroid cells as shown by western blotting and bone marrow smears, and compared to sections stained ...

Our aim was to investigate the effect of Withaferin-A on bone marrow micronucleus frequency and buccal mucosa detoxication agents during 7, 12-dimethylbenz[a]anthracene (DMBA) induced hamster buccal pouch carcinogenesis. Oral squamous cell carcinoma was developed in hamsters' buccal pouches by painting 0.5% DMBA in liquid paraffin, three times per week for 14 weeks. We observed 100% tumor forma...
